通常1-5営業日で発送：学校や予備校、学習塾など日本の教育現場で最も多く使われているおなじみの【ダストレスチョーク】の蛍光チョーク。一般に蛍光顔料はホルムアルデヒトを含有するものですが、当社製品は全ての色が基準値内に収まっており(基準値100/1以下)安心してお使いいただける。くっきり明るい発色なので、暗い部屋や夕方、夜間のご使用に最適。主原料は歯磨きにも使われる炭酸カルシムなので体にも安心、安全にご使用いただける。石膏チョークに比べ2倍以上長く使用でき経済的。また、北海道で年間40万トンの廃棄に困っているホタテ貝殻のリサイクルに成功し、ホタテ貝殻の微粉末が10%配合。ホタテ貝殻配合によって、よりソフトに、より鮮明に描けるようになり、粒子が重いので粉の飛散も少なくなった。持ち手部分にはコーティングが施されており、てに粉がつきにくくなっている。グリーン購入法適合商品、北海道リサイクルブランド認定商品、2010年農林水産大臣賞受賞商品、2011年文部科学大臣発明奨励賞受賞エコプロダクツ大賞審査委員特別賞受賞商品
